        This is a quality scoring program that compares two multiple sequence
        alignments: an alignment to be evaluated (the "test"
        alignment) and a second alignment that is believed to be correct (the
        "reference" alignment). The program outputs the following
        scores:
         - The PREFAB Q score (aka the Balibase SPS score or the
        Developer score). 
        - The Modeler score 
        - The Cline et al. shift score 
        - The Balibase TC (total column) score
